Have managed customer transaction data efficiently and supported high-demand workloads with reliable performance
The integration between data warehouse could be improved. Nowadays, a lot of data is getting generated, so certain ETL flexible scripts with backend database integrations would be an improvement I could see. I will not be able to clearly say there is currently a deficiency there. All our DBs are integrated with a backend data warehouse, not necessarily AWS. When third-party data warehouses are integrated, we are seeing some ETL job performance issues. It is a one-off scenario so we have not thoroughly done any troubleshooting on that. It could be platform or third-party related issue. From the AWS standpoint, if robust integration and data warehouse integration specific tools are added in the advanced suite, that would definitely be helpful.

Vector search has improved e‑commerce relevance but setup and learning curve still need work
Vespa definitely had its own set of challenges. It was really hard to get into initially, especially when I started implementing it in 2024 along with one junior employee, and the lack of documentation made it difficult. I aimed for an implementation with ColBERT, a sparse embedding mechanism, which I believed would fit well for e-commerce. We went through iterations during A/B testing because the initial set did not work as expected, which extended the process to about one and a half years. Vespa has a considerable learning curve, making it challenging for most people to get into, and it is also expensive, which can deter startups or those with smaller budgets from using it. Community support was decent, and we turned to it for clarifications. However, substantial improvements in documentation are necessary, especially more examples for handling DSL effectively. Having a runtime testing feature would greatly facilitate quick iterations.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"One of the first things I noticed when I had my first experience with MongoDB was how easy it was to use. I was expecting more difficulties or at least some challenges, but it was very, very easy to use. It's great technology, performs well, and is very convenient."
"Its flexibility, and cost. It is reasonably priced."
"The solution is user-friendly with a good object retrieval feature."
"My impression is that the initial setup is straightforward."
"The solution has good flexibility and very fast performance for searching data."
"The aggregation framework is very powerful when elaborating on data."
"It is convenient to use because we can do manipulations with the JSON data that we get, there are a lot of joins and associations with MongoDB, which makes it easy to use for us, and there is also a lot of transaction-related support from MongoDB."
"We can define security rules at the database level or the cluster level to grant or deny access to particular users."
"The best feature to me is the LTR feature, the ranking feature to be specific."
"Vespa is very good and it improves our product, and we got more clients."
"While conducting A/B testing, Vespa seemed to be performing slightly better than Elasticsearch, especially in search relevancy within live production systems, and its performance was decent."
 

Cons

"MongoDB should better support small and medium companies. There are a lot of clients out there that are interested, however, they need something lighter and less complex and something not so expensive upfront."
"More stable indexes would be helpful in a future release. That's been an issue for some time. I don't know if it's been fixed now but we transitioned to it because we needed a search index to be able to search for things and if that goes or starts disappearing, we have to move away from that solution. I don't know if they fixed it, last time I had this issue was three years ago so they might have solved it."
"The performance of the solution could be improved."
"I suppose it could be a little more secure."
"It could be more stable. It would be better if it were more user-friendly like Oracle, which is very easy."
"MongoDB could be more secure."
"A normal Oracle or database tester will take some time to gear up to MongoDB because the way of writing queries is different in MongoDB. There should be some kind of midway where a person who is coming from an Oracle background can write a query and get a response by using something like a select * statement or other such things. There should be some way for MongoDB to interpret these commands rather than making a person learn MongoDB commands and writing them. I struggled while writing these MongoDB commands. I had not seen such queries before. It was pretty difficult to get them. This is one of the areas where it would help from the improvement standpoint."
"I think that MongoDB's search engine should be improved."
"The integration is actually a pain."
"We want Vespa to implement some UI features so that we can visualize how our data goes and what embeddings it stores."
"Vespa has a considerable learning curve, making it challenging for most people to get into, and it is also expensive, which can deter startups or those with smaller budgets from using it."
 

Pricing and Cost Advice

"MongoDB's pricing is reasonable."
"MongoDB has a free version. You can also buy the enterprise edition, which is cheaper than Oracle."
"If you want support with the solution you will need to purchase a license and not use the open-source version. The license is a little expensive."
"I only used the open-source version."
"There is an annual subscription for the use of this solution."
"We use the open-source version, which is available to use free of charge."
"It is rather expensive."
"MongoDB is an open-source product."
